Electric surgical Bed manufacturers think, first of all to determine whether the solenoid valve failure, the method of judgement includes two kinds: one is to use a three-meter measurement of resistance, the other with metal to see if there is suction. Of course, if the solenoid valve suction action is normal. The problem can also occur when the oil circuit is blocked.

Then determine if the compression pump is faulty. First check the compression pump on the voltage is not, with a three-meter-scale compression pump resistance, if the foregoing are normally the commutation capacitor failure. The Electric operating table has an action in one Direction and no action in the other direction. Unilateral no action fault is generally caused by electromagnetic directional valve. Electromagnetic reversing valve failure may be the control circuit caused by bad, also may reversing valve mechanical card die. The specific check method is the first quantity reversing valve has no voltage. If the operating bed voltage to the reversing valve apart cleaning.

Because of the long-term use, change the valve active axis tens of thousands of a little impurity will cause the shaft to die, causing the operating table only one Direction of action. The use of the operating table will automatically drop down, but the speed is very slow. This situation occurs in the mechanical operating table more, mainly the lifting pump fault. The use of the operating table after a number of years may occur very small impurities stranded in the entrance valve, resulting in a small leak. The solution is to take the lift pump apart with gasoline cleaning, especially to check the oil intake valve.
